About Metres per second squared

The metre per second squared (m/s²) is the SI coherent derived unit of acceleration, defined as Δv/Δt (m/s per s). It makes Newton's second law F = ma dimensionally consistent with the newton (1 N = 1 kg·m/s²). Key reference values: standard gravity g₀ = 9.80665 m/s² (exact); ISS centripetal acceleration ≈ 8.68 m/s²; Falcon 9 max axial load ≈ 49 m/s² (5 g₀); human tolerance limit for sustained acceleration ≈ 30 m/s². All SI engineering and simulation software uses m/s² as the native acceleration unit. 1 m/s² = 100 Gal ≈ 0.102 g₀ ≈ 3.281 ft/s².

About Standard gravity

Standard gravity (g₀) is defined as exactly 9.80665 m/s² by the 3rd CGPM (1901), chosen to approximate surface gravity at ~45.5° latitude. It is the universal reference for human g-tolerance: fighter pilots sustain up to +9 g₀ with G-suit; sustained +3 g₀ causes greyout unprotected; F1 drivers experience +5 g₀ lateral and -4 g₀ braking. Pound-force is defined as 0.45359237 kg × g₀ = 4.44822 N (exact). Rocket specific impulse in seconds = thrust / (mass flow × g₀). 1 g₀ = 9.80665 m/s² = 980.665 Gal ≈ 32.174 ft/s² ≈ 35.304 km/h/s.
